Key findings from CPU/allocs/heap profiling: - LogAccess consumes 16.36% cumulative CPU (top app-layer hotspot) - os.statNolog dominates 74.95% of allocations (static file path checks) - net.IP.String + net.JoinHostPort account for 9.34% allocations - bufio.NewReader/Writer hold 54.6% of heap memory Includes detailed optimization priorities and next steps.
